This is just Kotlin. Strongly typed, more concise than Java or Go (and probably Typescript), less likely to blow up at runtime than Typescript, epic tooling, plenty of public code, and a library for basically anything because JVM.

And needs the JVM to start for 1.5s before you get any results. Sure.

Golang or just shell scripts.

The JVM takes tens of milliseconds to boot up, not a second and a half.

Obviously it depends on a bunch of factors but -- not on my machines. They are all with Intel and AMD CPUs and I don't use M-series Macs.

Never saw an instantly starting JVM in my life though.

Java runs a Hello World, cold, in a packaged JAR, in about 40ms. What you've seen isn't JVM startup but programs that do a lot at initialisation (like MS Word), as many Java programs like to do (because they often expect to run for a long time, so they don't care about startup time).

I have not worked with Java in a long time but I seem to remember that most Java programs also accrue a good amount of dependencies and some of them have their own init routines.

That adds up, fast. No idea how is it nowadays, admittedly. Maybe a ton of optimization work was done.

Yes, between Java 8 and modern java there were changes to the GC, startup time, JIT and probably more.

If you want, it java should now start pretty quickly.
